Yeah, being in the physically most prominent role, and being in the mentally dominant role… not the same thing.

You could also be a ‘power bottom’, where you’re receiving, but you’re mentally and physically dominant in the encounter.

You could also basically be bullied into being a ‘service bottom’, though I’m not sure that’s a widely used phrase.

Also, if you were doing something like cowgirl, as a service bottom… well you’d physically be on top of them.

You see this is all very straightforward and not at all confusing.
